Abstract

A device for making a carbon nanotube film includes a substrate having a surface, and two substantially parallel slits defined on the surface of the substrate. The two substantially parallel slits extend into the substrate from the surface of the substrate. A growing surface is defined by the two substantially parallel slits and located between the two substantially parallel slits.

Claims

1. A device for making a carbon nanotube film, the device comprising:

a substrate having a surface, wherein the material of the substrate is glass, quartz, silicon, or aluminum oxide;

two first slits defined on the surface of the substrate, wherein the two first slits are substantially parallel and extend into the substrate from the surface of the substrate, and the first slits are along a first direction;

two second slits defined on the surface of the substrate, wherein the two second slits are substantially parallel and extend into the substrate from the surface of the substrate, the two second slits are along a second direction, the two first slits intersects the two second slits and a growing surface is defined and surrounded by the two first slits and the two second slits; and

a carbon nanotube array located on the growing surface, wherein the carbon nanotube array is configured to have a carbon nanotube film drawn therefrom.

2. The device of claim 1, further comprising a catalyst layer on the growing surface.

3. The device of claim 1, wherein the substrate is a circular substrate.

4. The device of claim 1, wherein a residual surface is located beyond the two first slits and the two second slits, and the growing surface is separated from the residual surface by the two first silts and the two second slits.

5. The device of claim 1, wherein the first direction is perpendicular to the second direction.

6. A device for making a carbon nanotube film, the device comprising:

a plane substrate having a surface, two first slits spaced with each other, and two second slits spaced with each other, wherein the two first slits and the two second slits extend into the substrate from the surface, the two first slits intersects the two second slits, a growing surface is defined and surrounded by the two first slits and the two second slits, and the material of the substrate is glass, quartz, silicon, or aluminum oxide;

a catalyst layer located on the growing surface; and

a carbon nanotube array located on the growing surface, wherein the carbon nanotube array is configured to have a carbon nanotube film drawn therefrom.
